Flirty is an emotion available in The Sims 4. Flirty can become Very Flirty. It occurs when Sims complete successful romantic interactions thus making further flirt interactions more successful. They can also take a Steamy Shower, eat Flirty Heart Cookies (can be prepared by Flirty Sims with sufficient Cooking skill), drink Cupid's Juice, Research Pick-Up Lines on a computer or watch the Romance channel to become flirty.
